Phar::offsetSet

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)

Phar::offsetSet — Set the contents of an internal file to those of an external file

说明

public Phar::offsetSet(string $localName, resource|string $value): void

注意:
此方法需要将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.

This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets. offsetSet is used for modifying an existing file, or adding a new file to a Phar archive.

参数

localName: The filename (relative path) to modify in a Phar.
value: Content of the file.

返回值

No return values.

错误／异常

if phar.readonly is 1, BadMethodCallException is thrown, as modifying a Phar is only allowed when phar.readonly is set to 0. Throws PharException if there are any problems flushing changes made to the Phar archive to disk.

范例

示例 #1 A Phar::offsetSet() example

offsetSet should not be accessed directly, but instead used via array access with the [] operator.


<?php
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
try {
    // calls offsetSet
    $p['file.txt'] = 'Hi there';
} catch (Exception $e) {
    echo 'Could not modify file.txt:', $e;
}
?>

注释

注意: Phar::addFile(), Phar::addFromString() and Phar::offsetSet() save a new phar archive each time they are called. If performance is a concern, Phar::buildFromDirectory() or Phar::buildFromIterator() should be used instead.
